LUBRICATOR.`

p To all whom it may concern:

ln my improved construction the casing is simplified, the' oil cylinderis placed upright, the steam `chest is extended and improved, a directemergency feed is added, and other modifications of structure are made.

My invention consists 'in' the novel arrangement of the various parts,as hereinafter described, particularly pointed out in the claims, andshown in' theaccompanying drawings, in which- Figure 1 is a' perspectiveView of my device; Fig.v 2, a vertical cross-section through the centerof the oil cylinder, showing a part in elevation; and Fig. 3, a verticallongitudinal section on the line 3 3 of Fig. Q, showing the cylinder inelevation.

Similar characters ofreference refer to similar pa rts throughout theseveral views'.

ln the drawings, the oil cylinder M is setl' vertically upon a'bracketO, fastened on the `boiler A. 0n the top and along one side of thecylinder M, and integral therewith, is the steam chest L, into the topof which leads the steam pipe YI from the boiler A.

0n the top of the cylinder and to one side of the steam chest L is theoil cup P (Fig. 1),

whereby oil is introduced into the oil cylin- I der M On the side oftheoil cylinder M oppositethe steam chest and integral therewith is thecasing N, having a large lower receptacle, a vplurality of intermediatereceptacles Z', and a plurality of upperreceptaclesv X'. across the uper part of the casing N so that the water, o condensed steam may beadmitted under pressure into any part thereof. From the upperchambcrsX', the pipes G, G', and G2 lead toward the parts to be lubricated. Fromthe lower chamber corresponding pipes also lead toward the parts to belubricated, and each pair of upper and lower pipes run into the commonpipes H, H', and' H2 which lead directly to the parts to be lubricated.

In the operation of the lubricator, after oil has been introduced fromthe steam chest to each of the The steam chest L' extends Speeication o!Letters Patent. Patentd M31. 14, 1911. Application filed December 16,1909. Serial No. 533,368.

through the oil cup l, steam is admitted to the steam chest L throughthe pipe I, condenses into water, and is held under pressure by thesteam pressure in the boiler. The valve J' admits the fluid under lowthe piston. ward and the oil passes through the passage lV into thelower chamber of the casing N. The needle valves If, F', and F2, or anyof them, are opened, and oil passes up the small tubes S, S', and S2into the intermediate chambers Z', atthe ends of each of which are pairsof bulls-cye glasses D, D','and D2, for viewing the upward passage oftheoil. From these intermediate chambers Z' the pipes T' lead npwa'rdthrough the upper parts of the casing into 'the chambers X'respectively.` Condensed steam is admitted pi es T' through the passagesU U',and U2, y the valves C, C', andfC2. ''he condensed steam intheintermediate chambers Z" causes the oil to rise to the upper parts ofthe pipes T' beyond the 'valves C, C', and 02j The valves -B, ]3', andB2 'are then opened and mingled water and oil are forced into thechambers X' and through the passages V' into the conducting pipes G, G',and G2, and through them and the pipes H, H', and H2 to the part orparts to be lubricated. No oil can get intov the boiler through the pipeI, bccause the water in the chest L holds any oil which m'a'y escapebackward through the yalves C, C', and C2 inthe upper part of the chestL. v v

For emergency purposes the pipes H-,H'g and H2 are extended directlyinto the lower chamber of the casing N and are there controlled by thevalves E, E', and E2, whereby oill may be fed direct without the mixtureof steam into an Y one of the pipes H H', or H2. Thus, i any one or moreet the glasses D, D', or D2 are broken, there will be no interruption inthe lubrication of any part. Cocks R and R' are provided for thepressure to the cylinder be- The piston Q is forced up-4 the cylinder Mand the casing respectively for draining them out. The piston Q restsupon a support set. upright on the bottom of the cylinder M. Throughthis support a passage leads dow to the cock R. This ar.- rangement ofthe liiston, support, and draining passage, .prevents oil leaking fromthe f upper part of the cylinder into the drainage when the piston, Qrests upon the support so as to cover the draining passage.' Whenl it isdesired to clean the oil out of the lubricator, the valve J is openedand steam blown through the upper part ofthe cylinder M,. the lower,`chamber of the casing N and out the cock R. In the sides of the cylinder:M

are provided the sight glasses K and K.

I do not-limit myselfto the exact form in which my invention is hereindisclosed any further than is indicated in ythe following' f per portionof said chamber.

2. In a lubricator, 1n combination, an upright oil cylinder, a pistontherein, 'a chamber connected withthe upper portion of said cylinder, areceptacle for water of condensaconnection w1th the chamber,
